The purpose of the research was to explore emotional factors in adolescents with obesity and according to the findings to make psychotherapeutic recommendations. To know the emotional life and significant relationships of these adolescents four diagnostic instruments were applied: a clinical interview, TRO, PBI and OQ45, on two groups of adolescents (with and without obesity diagnosis, study group and control group respectively), with an n=25. The results showed that obese adolescents presented psychological symptoms, anxiety and depression, as well as a difficulty tolerating and handling intense emotions related to previous failures coming from the parental context.
